A novel and low cost electrochemical sensor for ceftazidime and cefazoline as antibiotic drugs based on nickel/SDS-poly(o-aminophenol) modified electrode

Pd@TTF Tailored Nanostructured Platform: Voltammetric Estimation of Ceftazidime

“…Till date, this is the broadest linear calibration range for CFZ determination by electrochemical method. Detection limit and linear calibration of the proposed sensor together with previously published literature is tabulated in Table . From table 1 it is clear that the analytical performance of the prepared sensor is comparable with previously reported literature.…”

Enhanced luminol–O2 chemiluminescence reaction by CuO nanoparticles as oxidase mimics and its application for determination of ceftazidime

“…The limit of detection (LOD) was calculated as recommended by Miller and Miller (using 3s of the blank signal) 49 and was found to be 2.5 Â 10 À8 mol L À1 . The LOD of the method was acceptable as compared to that of the previously reported spectrophotometric (LOD, 4 Â 10 À8 mol L À1 ), 4 HPLC (LOD, 4.3 Â 10 À7 mol L À1 ), 6 uorimetric (LOD, 1 Â 10 À8 mol L À1 ), 9 electrochemical (LOD, 1.8 Â 10 À6 mol L À1 ), 10 and chemiluminometric (LOD, 2 Â 10 À8 mol L À1 ) 11 methods. The relative standard deviation of the method was calculated upon four replicate determinations of 2.5 Â 10 À7 mol L À1 CFZM and was equal to 4.5% which shows satisfactory precision of the method.…”

“…It is mainly eliminated from the consumers' body through renal excretion. 1,2 CFZM has been analyzed in pure form, various pharmaceutical dosage forms, and in biouids taking advantage of different analytical methods including spectrophotometry, 3,4 highperformance liquid chromatography (HPLC), 5,6 high-performance thin-layer chromatography (HPTLC), 7 liquid chromatographymass spectrometry (LC-MS), 8 uorescence spectrometry, 9 electrochemical sensors, 10 and chemiluminometry. 11 The above mentioned methods share one or more drawbacks such as low sensitivity, narrow linear working range, expensive and sophisticated instrumentation, employing complicated mathematical operations, using toxic and environmentally hazardous substances, and needing time-consuming and laborious procedures for sample preparation and analysis.…”
